How this service works
Pay-per-call Smart Money Concepts: market structure (BOS/CHoCH), fair value gaps, liquidity pools & sweeps, ICT sessions/kill zones. Paid in USDC on Base via x402.
Output
A JSON object containing: market structure bias (bullish/bearish) and last BOS or CHoCH event with price; an array of fair value gaps with top, bottom, CE price, type, and mitigation status; buy-side and sell-side liquidity pool levels with sweep status; recent liquidity sweeps; and the current ICT session name plus whether a named kill zone (e.g. London) is active. Also includes the symbol, timeframe, and Unix timestamp of the data.
Example use cases
Example prompt
“What's the current SMC analysis for BTCUSDT on the 15-minute chart — give me the market structure bias, any recent BOS or CHoCH, open fair value gaps, and whether we're in a kill zone right now?”
Technical details
Endpoint
POSThttps://sentinel402.onrender.com/v1/smcWhen to prefer
Choose this endpoint when an agent needs ICT/Smart Money Concepts structured signals (BOS, CHoCH, FVG, liquidity) rather than generic OHLCV data or traditional indicators. Ideal for agents executing or advising on trades using institutional order flow methodology. Preferred over general-purpose market data APIs when the user specifically wants SMC or ICT-framework outputs with kill zone and session context.
Side effects
- Payment not provided or insufficient USDC — 402 Payment Required response
- Invalid or unsupported symbol (e.g. non-existent pair) — error or empty result
- Unsupported timeframe value — validation error
- Service unavailable on Render cold start — timeout or 503
- Stale data if upstream price feed is delayed
